WIPO Patent Application WO/2017/101757
Kind Code:
A1
Abstract:
A foldable tray, comprising a baseplate (100), and a first side plate (200) and a second side plate (300) symmetrically arranged on any two sides of the edge of the baseplate (100). The first and second side plates are both hingedly connected to the baseplate (100), and are flatly placed on the baseplate (100) after being folded in an overlapping manner. The first and second side plates are height-adjustable side plates. An extension side plate (500) that can be stretched out from the interior of the side plate is arranged at the top of each of the first and second side plates. The stretching height of the extension side plate (500) is controlled by a prepositioning apparatus (600) arranged in each of the first and second side plates. A side plate folding lock (700) is arranged on each of the first and second side plates. The tray further comprises roller shutter side plates (800) symmetrically arranged on the other two sides of the edge of the baseplate (100). The roller shutter side plates (800) are rolled in roller shutter apparatuses (810) located in the baseplate (100), and can be pulled out under the action of external force; and when the external force disappears, the roller shutter side plates can automatically retract. The tray is simple in structure, convenient to use, easy to fold, free of occupied space in storage, and has good stability, high strength, and a wide application range when being in use.
